Anyone who has ever used injection drugs should get tested for hepatitis C, according to new draft health guidelines released today.

The guidelines are an improvement according to critics, but don’t go far enough. The guide from the U.S. Preventative Task Force failed in not recommending testing for baby boomers, people born from 1945 to 1965, according to the National Viral Hepatitis Roundtable.

The Centers for Disease Control and Prevention already recommends baby boomers get a one-time test for hepatitis C. That age group of Americans accounts for 75 percent of the hepatitis C cases in the United States.

The CDC estimates that if everyone born from 1945 to 1965 were tested, more than 800,000 cases would be identified.

But the task force guidelines say there is only “small benefit” for testing baby boomers.

Most people with hepatitis C do not know they have it. Yet they are at increased risk for liver cancer, liver disease and death. The leading cause of infection is IV drug use.
